T1039: Data from Network Shared Drive
Adversaries may search network shares on computers they have compromised to find files of interest. Sensitive data can be collected from remote systems via shared network drives (host shared directory, network file server, etc.) that are accessible from the current system prior to Exfiltration. Interactive command shells may be in use, and common functionality within cmd may be used to gather information.
How it's found
Detection Strategy for Data from Network Shared Drive: Monitoring of file access to network shares (e.g., C$, Admin$) followed by unusual read or copy operations by processes not typically associated with such activity (e.g., PowerShell, certutil). Unusual access or copying of files from mounted network drives (e.g., NFS, CIFS/SMB) by user shells or scripts followed by large data transfer. Detection of file access from mounted SMB shares followed by copy or exfil commands from Terminal or script interpreter processes.
